Answer:

63.7 inches

Step-by-step explanation:

half the base is 9 inches, so the equal legs are each

L = √(9² +21²) = 22.8473...

Perimeter  = 2(22.8473) + 18 = 63.6946... ≈ 63.7 inches.

____× 105 is 3,000 times greater than 2.3 × 102 and is _____ times greater than 1.38 × 101.
musickatia [10]
For this case we must calculate the values of the unknowns.
 We have then:
 x * 10 ^ 5 is 3,000 times greater than2.3 * 10 ^ 2
 We have the following equation:
 (x * 10 ^ 5) / (2.3 * 10 ^ 2) = 3000

 From here, we clear the value of x:
 x = (10 ^ 2/10 ^ 5) * (2.3 * 3000)

x = 6.9
 Then, on the other hand we have:
 "and is _____ times greater than 1.38 × 101"
 That is, we have the following equation:
 (6.9 * 10 ^ 5) / (1.38 * 10 ^ 1) = y

 The value of y is:
 y = 50000

 Answer:
 
6.9 × 105 is 3,000 times greater than 2.3 × 102 and is 50000 times greater than 1.38 × 101.

Answer:

Part A: See detail below.

Part B: Company B charges less than company A for 8 windows.

Part C: The saving using company B for 6 windows is $3.

Step-by-step explanation:

Part A:

Company A: (total charges) = ($6)x(N number of windows)+($12)

Company B: (total charges) = ($5)x(N number of windows)+($15)

Part B:

Company A for 8 windows: 6*8+12=$60

Company B for 8 windows: 5*8+15=$55

Part C:

(Saving) = (6*6+12)-(6*5+15)=48-45= $3

A local Ace Hardware sells batteries ($3) and small boxes of pens ($4). In August, total sales were $976. Customers bought 4 tim
AleksandrR [38]

Step-by-step explanation:

let us assume the amount of battery boxes as 3x and pen boxes as 4x

since the battery sale is 4 times more,

3 (4x) =12 x

so 4x +12x = 16x

total money received is 976 rupees

so 16x =976

x =976÷16 = 61

AMOUNT OF BATTERY BOXES =4X = 4×61= 244 BOXES

AMOUNT OF PEN BOXES = X= 61 BOXES
